Biotic Factors:

Many plants and animals exist in the desert, contrary to popular opinion that deserts are desolate and sustain little life. Scorpions, coyotes, snakes, spiders, lizard, and cacti are just a few of the biotic factors.

Abiotic Factors:

Sand: The soil of a desert is maily comprised of vast sections of sand spanning over miles of land. The sand is dry and not mineral rich, enabling very little plant life to thrive on its foundation. Sometimes in cold deserts, moss and grass will join sand to make up the land and create very mineral-rich soil.
(Lack of) Moisture: Precipitation of deserts vary. Depending on if the desert is dry, semiarid, coastal, or cold, the amount of rainfall is different. Hot and dry deserts yield usually only yield less than 10 inches or rain per year. Cold deserts may not receive much more, but it could be in the occasional form of snow as opposed to rain.

A habitat is the natural home or environment of an animal, plant, or other organism.A niche is a shallow recess, especially one in a wall to display a statue or other ornament.
